Hi guys, I have aquired a 1978 911 SC that I am rebuilding and restoring. I have done two 356's but this is my first 911. I have the engine out and completely dis-assembled except for the cylinder heads. Everything is clean inside and the crank, rods, cylinders and pistons mike within specs. However there are seven broken cylinder studs, all on the exhaust side. The top studs are all good. The top studs are magnetic and I assume carbon steel. The bottom studs are non magnetic. I will have case savers installed for the bottom studs and am thinking of keeping the top studs as they are. What type of studs should I put in the bottom exhaust side? I plan on getting rid of the CIS injection and going to PMO carbs, keeping the pistons and cylinders with new rings and SSI exhaust. Haven't thought much on what to do with the cams. They are four bearing cams. This will be a street car and I would like a nice torquey engine. I will to keep the red line under 7000. Your advice will be much appreciated. Regards, John
